Leaves and grit can slow a patio drain and leave water standing on slippery pavers. Cleaning the grate and accessible channel before heavy rain keeps the surface safer.
Lift the grate safely
Wear gloves and use the intended lifting point. Do not force a corroded grate or place fingers beneath an unstable edge.
Remove loose debris
Brush out leaves and sediment, then inspect the channel for roots or compacted mud. Keep debris from being pushed farther into the drain.
Rinse and observe
Use a modest flow of water and watch whether it moves away freely. Standing water, a broken channel, or repeated blockage may need a drainage professional.
Maintain the area
Sweep nearby paving during leaf fall and keep soil or mulch from washing into the grate.
